as well as Windsor shuttles, maybe more.

ITYF that Sarah Siddons is electrically a bit more basic than a modern
locomotive and the necessary mods were mostly concerned with the
voltage rating of cable insulation and providing a method of altering
the current return path; these might have been dealt with at marginal
cost during one of its overhauls during "retirement". I don't recall
anyone mentioning what was done about the motors, if anything.

I think I have read before (in uk.railway) that all LU stock is being
or has been rewired whenever rewiring is needed to accept 750 V DC
simply as thats the standard and its cost no difference to lover
vales.

AFAIK it has bog standard MV339s.

Now older 4Sub had MV339 and they were not allowed - I think - west of
Pirbright Junction because of the BOMO line nominal higher voltage
(which certainly has been explained in detail by Richard Catlow) .
EE507 4Sub - which was really all the ones that survived into the
1970s were (again I think, I am not certan) OK. Not that 4sub had much
occasion to run west of Pirbright anyway apart from possible access to
Eastleigh works.

I've been down Sole Bank in a 2-BIL. Ran OK but blew a few light bulbs.

hence on her tours on the Southern she operated
coupled to some older Southern Units which provided the air for
braking .

Not always.

I think it was only open day shuttles where it worked like that - I'd
possibly go as far so say there were more tours in LH form than with
other EMU.

The tours I cited used SR Mk.1 AB stock - well at least the Portsmouth
one did as I was one it, and here a pic
